Andrew Siegel, MD | Founding Director

Andrew is an Assistant Professor of Clinical Psychiatry at the University of Pennsylvania Perelman School of Medicine. In 2013 while walking home from work one evening, a homeless man at a busy intersection asked him for money. Feeling powerless to help in any meaningful way, he began to dream up a solution, one that would not only allow him to contribute to the short term needs of the homeless panhandler, but would simultaneously support that individual's path to stable housing.

Dan is a Senior Research Fellow at the University of Pennsylvania’s School of Social Policy and Practice and an Affiliated Researcher with the Department of Veterans Affairs’ National Center on Homelessness among Veterans.

He has a PhD in Social Welfare from the University of Pennsylvania and a Masters in Public Policy from Harvard's Kennedy School of Government. In his capacity as Managing Partner, Dan brings his considerable wealth of knowledge and experience to bear in leading StreetChange in its mission of improving the lives of our most vulnerable city residents.

Michael is the President and CEO of the Mental Health Association of Southeastern Pennsylvania (MHASP). StreetChange is proud to partner with Michael in furthering the mission of MHASP: "To promote groundbreaking ideas and create opportunities for resilience and recovery by applying the knowledge learned from the people we support, employ, and engage in transformative partnerships."

MHASP is a leader in delivering services by and for people in recovery with a behavioral health diagnosis, based on the principle that self-help and mutual support are empowering and that the best helpers for those in need are often those who have experienced similar challenges. Their recovery based practices and programs offer a model of service delivery that emphasizes peer/family support demonstrating that recovery from mental illness and/or substance use addictions is possible. These services are designed to empower people with behavioral health diagnosis and their families so that they may lead self-fulfilling lives.

MHASP serves over 4,000 people annually in the five county region of Southeast Pennsylvania, providing peer-to-peer services to adults with a behavioral health diagnosis, targeted case management services to the same population and family support and advocacy on behalf of families whose children have been diagnosed with a behavioral health condition.

MHASP also operates three homeless outreach teams, two of whom are based in Philadelphia, the other in Delaware County.
